Hello,
My Samsung TV D6200 has a strange issue.
I recently change the motherboard because of NAND issue. New motherboard works... but only if I unplug the front button/IR PCB. If I plug this one, the TV shut off and did not respond nor remote or front buttons. The red standby LED is also off. When I unplug the front PCB from the motherboard, the TV power up and works flawlessly... but I can't change source/channel and go to menus.
The front buttons PCB seem to be OK, have you an idea on how fix this issue ?
Thanks !

Re: D6200 front pannel buttons and IR remote nor working
You probably need to restore some values from former mainboard service menu (such as TV model/type if different, or "num of panel key" for example). Also factory reset could help (then, or at all).
I do NOT receive any PM. Please use forum.

OK, first thanks for your help !
Is the reset may cause a brick ?
Can I control the TV through network or other way than remote/front buttons ?

Right, without remote control won't be easy actually
Solution might be an eeprom reset (check wiki for how-to).
In case you worry, your tv is already kind of brick with no rc anyway

Yes but, actually the TV works. I have an image and HDMI sources are detected and switch automatically. But for that, I need to unplug front IR/buttons PCB.
Before actual working motherboard, I already tested 3 mobo for repairing this TV, this working motherbord is pulled from the exact same model (D6200) and I don't understand why is does not work with RC/button.
I notice, where I power up the TV by plugging it to AC, the TV not showing "Smart TV" logo and go directly on previous channel/source used. Ethernet interface seem to be disabled too.
EDIT : I made the reset thing. I saw the Smart TV logo upside down and message to setup region and others things. But the IR/fronts buttons still not responding. I will try with a new front PCB.
